The ZR-7 was first introduced in 1999, although the engine specification could have been from 25 years earlier. That's because the ZR-7 is based around a slightly updated version of the Z750 engine of 1973.

 

The air-cooled four-cylinder engine is decidedly low-tech, but it offers economical, reliable running, with a lazy, flexible power delivery.

The chassis is more up-to-date, but not by much. A steel-tube cradle frame is more than stiff enough for the power, and a monoshock rear suspension unit is adjustable for preload. The twin-piston front brake calipers aren't peformance parts, but provide sufficient stopping power, and the modern tyre sizes allow decent sport-touring rubber to be fitted.

Grippy rubber just shows up the lacklustre nature of the rest of the chassis though, and the ZR-7 quickly runs out of ground clearance in fast bends.

 

However, the ZR-7 does win out in the equipment stakes. The fuel tank holds a massive 22 Litres (4.8 gal), the exhaust is long-lasting stainless steel and in addition there's a large storage space under the comfortable dual seat.

For 2001, Kawasaki launched a faired version of the ZR-7, the ZR-7S. While the small half-fairing certainly improved the bike's practicality and distance capability, the

extra weight didn't help either the engine or the brakes, and the ZR-7S was still outclassed by Suzuki's Bandit, Yamaha's Fazer and the faired Honda Hornet'S' in almost every way.

 

Kept in a low-performance commuting or novice bike role, the ZR-7 is just about up to the job. But it is the superiority of its competitors that relegates the ZR-7 to the bottom of many riders' list. Having said that, the ZR-7 has proved popular in some continental markets: extreme customized ZR-7s are, strangely, a common sight in France.
